LASTlNG-JACK.

SPECIFICATION forming part of Letters Patent No. 546,188, datedSeptember 10, 1895.

Application filed December 22, 1892- Serial No. 456,003- (No model.)

To azZZ whom it may concern.-

Be it known that I, CHARLES F. PYM, a subject of the Queen of GreatBritain, residing at Vindsor, in the county of Essex and Province ofOntario, Canada, have invented certain new and useful Improvements inLasting-Jacks, of which the following is a specification, referencebeing had therein to the accompanying drawings.

The invention consists, particularly, in the peculiar construction ofthe support for the jack-frame, whereby it may be adjusted in anydesired position,so that the operator can work upon the shoe to the bestpossible adr5 vantage in position as well as light, and regardless ofwhether the operator is 'a right or left handed person.

The invention further consists in the peculiar construction of theheel-post, and further in the peculiar construction, arrangement, andcombination of the various parts, all as more fully hereinafterdescribed.

In the drawings, Figure 1 is aside elevation of my improved jack. Fig. 2is a similar 2 5 elevation, partly in seotion,showing the last inposition upon the jack. Fig. 3 is a verti' cal section through the topof the standard, illustrating the construction of the joint between thestandard and bracket. Fig. t is a de- 0 tached perspective view of thefriction-block employed in the swiveled joint.

A shows the table or bench on which the jack is supported.

B is an apertured plate secured to the top of the bench and having thedepending semicircular socket O, to which are secured the clamping-boltsD, the heads of which enter a groove in the standard E, whereby thisstandard may be vertically adjusted to any de- 0 sired height. In thetop of this standard is the pin 13 of a head G. This pin is providedwith a groove H, in which is the semicylindrical friction-block 1,against which a set-screw l bears, which allows the head to swivel from5 the top of the standard,but prevents its accidental disengagementtherefrom.

J is a plate preferably formed integral with the head G and having thecentral circular stud .l' on one side thereof, upon which is pivoted abracket K. This bracket is held in its adjusted position upon this studby means of the clamping-bolt K, passing through the plate J and througha corresponding movable plate K upon the opposite side of the bracket,the two being clamped together by means of a winged nut L or in anyothersuitable manner. I preferably limit the movement of the bracket Kto its pivot by means of a lug M, formed on the plate and engaging in asemicircular groove in the bearing of the bracket, Go with a stop ateach end,so that when it is turned to the limit of its movement ineither direction it will be supported in that position by the lug Mbearing against the stop. This bracket at its outer end is provided witha circular bearing N, in which is swiveled a pin 0, formed centrally orsubstantially so of the jack-frame O. This pin is provided with a groove11 a corresponding semicylindrical block I, and a set-screw to hold theblock in 73 position, thereby allowing thejack-frame to be swiveled inthe bracket and prevent its disengagement therefrom.

The jack-frame is provided with an adjustable toe-rest P, and on itsopposite end with 75 the heel-standard P, preferably formed integralwith the lasting-frame. This heelstandard is centrally apertured toreceive a coil spring Q, which at its lower end is provided with anadjusting-bolt Q, having a suitable nut or other suitable means ofapplying tensiontothespring. 'lhisspringisexpanded and at its oppositeend is secured to the forward edge of the pivoted heel-pin block R,which is pivoted at its rear edge upon a pivot R, extending transverselyof the heel-post. This heel-pin block is provided with a suitable pin Sto engage in the last. The tension of the spring is suflicientto drawthe block R to the inclined position shown in Fig. 1, and the operator,engaging the pin S into the socket in the last and turning the last to asubstantially horizontal position, will put the spring under tension, sothat when the toe rests at the top of the toe'support the tension of thespring will hold it firmly in position. The result of this constructionis that I am enabled to adjust the last-frame at any point around thestandard, and at any point of adjustment I am enabled 'to adjust the toolast-frame itself at any angle to the standard, by turning the bracket Kupon its pivot and the last-frame upon its pivot. Part of theadjustability of the device is illustrated in dotted lines in Fig. 1,where the bracket is shown turned to a vertical position, the lastframeextending horizontally, and it is evident that it may be turned entirelyabout its pivot while in this position, or the entire device may beturned around to the left hand of the standard by simply turning thehead G upon its pivot.

WVhat I claim as my invention is- 1. In alasting jack, the combinationof the vertically adjustable standard, the head swiveled at the topthereof and provided with a pivot extending across the standard, abracket journaled on that pivot and adapted to swing over the standard,and a lasting jack frame pivoted in the end of that bracket,substantially as described.

2. In a lasting jack, the combination of the tubular standard, the headG at the upper end thereof, the pin F on said head entering the upperend of the standard and having a groove H and a semi-circular block Iengaging in said groove, the set screw 1 for looking the said block inposition, the bracket pivoted to the head and the lasting framesupported on the bracket, substantially as described.

8. In a lasting jack, the combination of the standard, the head Gswiveled at the upper end thereof and comprising the plate J, thelaterally extending apertured lug J, the plate K the bracket K journaledon the lug J and having a semi-circular groove in its outer face and alug N on the plate J, engaging in said groove, substantially asdescribed.

In testimony whereof I affix my signature in presence of two Witnesses.
